I emailed Paul Weitzel and he indicated that they do have a transistor model and it has 50db of gain (could be made with higher gain). I'm trying to get some other information, such as loading options, but he indicated this was probably suited to cartridges like Blue Point (I'm assuming maybe HO MC) and MM cartridges. He has been trying to come up with a step-up to use with the phonostage but so far has not liked the sonic results.
The website is pretty useless for information on new products and while I'm sure they would make the tube gear, the focus has been on transistors for the last couple of years. My D-225 amp is the best buy I've made in a while. I also have the Pre-1.5 battery power preamp, although I'm not using it in my system at the moment.
